TILE OR BRICK FOR FLOORS, 84,0.

SPECIFICATION forming part of Letters Patent No. 300,521, dated June 17,1884.

Application filed May 29, 1884. (No model.)

To (Lurch/0m it may concern.-

Be it known that I, THOMAS C. SMITH, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented anew and useful Improvement in Tiles or Bricks, of which thefollowing is a specification.

The purpose of this invention is to provide tiles or bricks the backs ofwhich are constructed with a lip and recess, so that upon placing themtogether in practical use they are locked, the one into the other, atthe extreme back surfaces, making each piece dependent upon the piece incontact with it for the better support and retention in its properplace.

My invention is applicable generally to tiles or bricks of any form. w

The drawings accompanying this specification represent, in Figures 1, 2,3, and 4, perspective views of different forms of tiles or bricks madein accordance with my invention.

Similar letters of reference indicate like parts.

A. is the body of the tile or brick, of suitable form and size, the backsurface of which is projected on one or two sides, as may be deemed bestsuited to the particular uses of the tile or brick, in the form ofa lip,B, pref erably made in the form of a quarter-circle, with a radius ofabout one-quarter of an inch. .The opposite sides of the tile or brick,at the back surface, are recessed, O, in corresponding size and form tothe lip B, so that when the tiles or bricks are placed together inconstruction the lip B of the one exactly fits into the recess 0 of theadjoining one, thereby securing each piece at its extreme back surface,and locking the whole together. In all uses of tiles the necessity oflocking them together so that the whole may be as nearly solid aspossible is readily understood, whether they be used for floors, walls,ceilings, or other purposes.

Having thus described myinvention, I claim. as new and desire to secureby Letters Patent- A tile or brick the back surface of which isprojected on one or two sides in the form of a lip, and theoppositesides of the back surface recessed to correspond with the sizeand form of the lip, substantially as shown and herein described.

THOR. C. SMITH.
